Expect traffic delays at Biggs this week, 11 p.m. to 5 a.m.

KERR Contractors is building a modernization project at the Biggs Junction Interchange, which will cause some rerouting at the interchange this week.

The project will significantly widen US97 and all of the interchange ramps. It also includes new retaining walls, bridges and signals. The work will take place in stages to minimize traffic delays. The first stage is occurring this summer, and includes constructing the West half of the new US97 bridges over Interstate 84 and the Union Pacific Railroad. The project will be completed in the summer of 2015.

From July 13 to July 19, the contractor will perform bridge demolition and work on ramp construction outside of the roadway. Bridge removal will occur at night to minimize the effects on traffic. Between the hours of 11 p.m. and 5 a.m. through Friday morning, Interstate 84 will be closed at the bridge.

Traffic will be routed up and over the bridge removal area using the existing on and off ramps. Flagging will be used during this time to manage traffic.

Delays during flagging operations will be 5 to 10 minutes. I-84 is reduced to one lane in both EB and WB directions. Speeds on I-84 through the work zone have been reduced to 50 miles per hour
